Over half of Brits that currently do not have broadband access are not interested in getting online, says Ofcom.
Ed Richards, chief executive of the regulatory body, also told the London School of Economics that of the 1.5 million people that are currently without internet access, 30 percent have their access restricted by financial resources, while 15 percent do not want it and don't have the resources.
"Even though people are bombarded by messages about the range of benefits of being online - whether buying cheap insurance or catching up on last week's soaps - there seems to be millions of people who are not yet persuaded," he said.
"We need to tackle this challenge as much as tackle the challenge of low-income households who can't afford access."
Richards' remarks come just months after the government unveiled its Digital Britain report. The report, which was commissioned by Communications Minister Lord Stephen Carter, laid down plans to offer every UK resident a minimum of 2Mbps broadband access.
